BACKGROUND OF THE INVENTION Field of the Invention

The present invention is related to electronic/digital construction-related plans, and in particular, to methods and systems of managing electronic construction-related plans.

Description of the Related Art

Conventionally, constructions documents are either hardcopy blueprint type drawings or relatively simple electronic drawings which provide a limited ability to associate or store data in association with such hardcopy or simple electronic drawings. Hence, conventional systems lack an adequate capability for the various entities involved in the production, approval and implementation of a construction project (e.g., architects, design firms, contractors, and public agencies, such as city plan approval agencies), to modify or comment on such plans. Further, conventional systems lack an adequate capability to locate and generate reports with respect to plan comments.

BRIEF DESCRIPTION OF THE DRAWINGS

The disclosed aspects will hereinafter be described in conjunction with the appended drawings, provided to illustrate and not to limit the disclosed aspects, wherein like designations denote the elements.

FIG. 1 illustrates an example system architecture.

FIGS. 2-21 illustrate example user interfaces.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS

Systems and methods are described for managing design related documents. For example, certain systems and methods may be used for managing building-design related documents, such as electronic construction documents, fix-it documents from plan checkers, etc., manufacturing documents, clothing design documents, or other types of design documents.

Certain embodiments enable a user to search, filter, and report on comments added to a documents, such as an electronic building related document, a manufacturing document, a clothing design document, or other design document (e.g., a document in portable document format (PDF) form, ISO 32000 compliant documents, XPF documents, etc.), such as comments by plan checkers added to a building plan submitted by an applicant to a government agency for approval or other design document needing approval. Certain embodiments further provide event driven notifications to one or more groups involved in the design and approval process. Certain embodiments further provide workflow process management and role based security.

Example embodiments will now be described with respect to the figures.

FIG. 1 illustrates an example architecture of a plan management system. It is understood that other architectures may be used with fewer, additional, and/or different components. The plan management system may include geographically distributed components and/or co-located components (e.g., servers, data stores, user terminals, etc.). The system may interact and communicate with systems of end users, such as terminals (e.g., general purposes computer systems, servers, tablet computers, smart phones, etc.) of plan checkers, project managers, architects, designers, etc. For example, the plan management system may include a network interface communicate with user terminals over a network, such as the Internet, a local network, or otherwise. The user terminals may include displays, input devices (e.g., keyboards, mice, trackballs, touch screens, microphones, etc.), speakers, printers, etc. The user terminals may host or have access to browsers or other interfaces configured to access resources, such as documents formatted using HTML or other formatting languages.

Referring to FIG. 1, an example architecture of the system includes a data layer, a business layer, and a presentation layer. The data layer may include a database in the form of an SQL (structured query language) database, and may store project/design drawings and associated metadata. The database may store drawing revision histories (e.g., including date of revisions, who made the revisions, what was revised, etc.), drawings in an originally submitted formats and/or in a converted formats. Optionally, a directory structure for cached files may be organized using drawing records' primary keys. The database may store standard comment libraries, user account information, user permissions, etc.

The business layer may include a rendering engine, a drawing printing component, and a service gateway. The rendering engine is used to render drawings and may be a multi-process, multi-threaded rendering engine. For example, the rendering engine may invoke libraries (e.g., Java libraries) for converting a master tile (e.g., a PNG master tile, wherein a given drawing may include one or more tiles or may be divided into two more tiles) into differently formatted tiles for consumption by a drawing review system. By way of further example, the rendering engine may read a PDF drawing file and convert it to a master tile. The drawing printing component may be configured to generate printable files in a PDF or other desired format. The service gateway may be used to expose an API (application programming interface) that may be invoked by routines executed in a user's browser. By way of example and not limitation, the API may respond with data objects, such as JSON (JavaScript Object Notation) or XML (eXtended Markup Language) data objects, as appropriate.

The presentation layer may include data management interfaces, a document submission component, a drawing review component, and a graphical charting component. The data management interfaces are configured to receive data (e.g., from user or API interfaces) and post data. For example, the interface may employ AJAX-based interactions with HTTP posts to the system and JSON requests back. The document submission component may be used to receive documents from users. For example, the document submission component may be configured to provide an external interface to routines executed by a user browser. The document submission component may be configured to provide the user browser with metadata regarding the submission and may enable multi-file submission by the user without requiring browser page refreshing. The drawing review component may be configured to input multiple tile layers from the rendering engine, and then generate one or more additional layers (e.g., multiple SVG (scalable vector graphics) canvases) to provide vector shapes, measurement tools, commenting, and other drawing review functionality. The graphical charting component may provide the user with interactive charts, as described elsewhere herein. Optionally, the graphical charting component may be configured to use a programming/scripting language to generate dynamic SVG canvases from JSON data fetched from the data layer.

In response to a user request, the system may queue a drawing to be rendered. When queuing the drawing, the system may write a configuration file (e.g., an INI file) that includes rendering instructions to a file system. The file system may date stamp the configuration file and/or the drawing, and may optionally act as a first-in-first-out queue with respect to queued drawings. The multi-process, multi-threaded rendering engine may access the configuration file corresponding to a drawing to be rendered. A given process may render a given drawing (e.g., a single drawing), and optionally each thread performs a separate zoom level and/or color version rendering of the drawing.

An example rendering process will now be described. Drawings are pulled from the drawing queue (e.g., one at a time), and then routed through a queue for a thread pool. An example thread pool management process enhances the rendering time of a given rendering request. In certain embodiments, the thread pool management process enables a rendering engine to service multiple portals (instances of the plan management application) on a given server, or optionally multiple portals on multiple servers. Thus, a physical server optionally may host multiple instances of the plan management application (portals), wherein a given instance may have a unique set of configurations and customizations. Multiple portals may share physical server resources, such as bandwidth, storage, and/or processing power. However, optionally, there is division of logical and virtual resources, such databases, drawing files, and uploaded user content. Optionally, a given instance of the plan management application is prevented from accessing some or all of the logical and virtual resources of another instance. Portals may also be accessed by a unique locator (e.g., a unique uniform resource locator (URL)) and have a target user-base as part of an organization, such as a business or agency. For example, the ‘portal’ may be the client's web URL where the plan management application runs. In a virtual machine environment, a single engine could service many ‘clients’. The queuing service enables multiple rendering engines to service one server or multiple servers.

An image manipulation service, such as that described below, may optionally be initiated automatically upon system startup, and halted during system shutdown. Optionally, the service operates independently of web applications or other services, but accepts instructions for handling requests.

At state 0, if a drawing has not already been pre-rendered, a virtual printer may be used to convert a drawing from one format to another format (e.g., from a PDF format to a gray-scale PNG Source Tile Image format). In certain embodiments, other renderings are obtained from the source drawing file. Once the source drawing is rendered, it does not need to be re-rendered, as other zoom levels or colors are prepared, optionally at substantially the same time as the source drawing is rendered. Thus, if a user, while later viewing the drawing requests a particular user-selected area of the drawing be displayed with higher magnification (“zoomed”), the system may substantially instantly access and display the previously rendered magnified area, without having to go through the time consuming process of performing the zoom processing and manipulation. Similarly, if a user later requests a selected drawing color, the system may substantially instantly access and display the drawing with the previously rendered selected color, without having to go through the time consuming process of performing the colorizing processing and manipulation. The source drawing may persist in solid state memory during a rendering instance, or it may be loaded into solid state memory from a copy stored on a magnetic or optical disk storage device.

In an example embodiment, the rendering includes dividing the source drawing image into tiles (e.g., 200×200 pixel tiles). In certain embodiments, a typical source drawing image may be between about 2,500 and 16,000 pixels in both the X and Y dimensions, although other pixel quantities and configurations may be used. The origin may be located at or towards the middle of the source drawing, and may be positioned at or towards the middle of a tile. As a result, in certain embodiments the collection of tiles may be an odd number tall and wide, with the same number of tiles left and right, and above and below, the origin. The following illustrates an example tile configuration:

000#000

000#000

###X###

000#000

000#000

At state 1, the source drawing image is converted into a colorized source. Optionally, even if the output is black, the source drawing image undergoes colorization. Colorizing may be performed by translating some or all pixels in the drawing image into a target color. For example, white may be converted into an alpha value of 0 (transparent), while solid black (#000000) may be converted to an alpha value of 255 (opaque). Variations of gray may be translated into respective alpha values. Then color(s) may be shifted into a requested spectrum and may be expressed as a RGB (red, green, blue) value or other color model value (e.g., CMYK). Thus, for example, in certain embodiments a given pixel is represented as a 24-bit (4 byte) object in memory, in an ARGB format. In ARGB format, each byte is a number between 0 and 255 (expressed using hexadecimal notation) representing the intensity of the alpha, red, green, and blue colors in the pixel. Given an incoming color request, each pixel's color is translated into the target color.

Color shifting may be performed via pointer walking by adjusting the bit value of each pixel at a very low level in memory. This process provides an extremely efficient color shifting process as it omits layers of abstraction and excess object instantiation by directly transforming the colors with a mathematical algorithm (and optionally, only a mathematical algorithm). Thus, in certain optional embodiments, the color changing is performed without using libraries to abstract out the logic, and instead directly accesses the references in memory to adjust the bits representing the pixel states. The colorized tile may remain in solid state/local memory during the rendering process, and optionally is not persisted to nonvolatile memory, such as a magnetic or optical disk device.

At state 2, for each of a plurality of target zoom levels, the colored source may be resized into a “master tile.” The master tile represents an image that is a percentage zoom of the source images, which is padded with tile spacing so that it rounds up to the nearest odd tile count.

Optionally, via a configurable setting, a given master tile may be persisted to disk or other nonvolatile memory. Optionally, by default, a master tile is not persisted to reduce storage consumption. The master tile may remain in memory during the rendering of this specific zoom level, and may be released to garbage collection after this zoom level's thread is complete.

At state 3, the master tile is cut (e.g., virtually divided) into vertical strips (e.g., vertical strips that are one tile wide). This cutting process may be performed using a pointer reference in memory representing a matrix of bits that make up the pixels.

At state 4, a given master tile vertical strip is cut horizontally, thereby preparing the specific tiles for rendering. This cutting process may be performed using a pointer reference in memory representing a matrix of bits that make up the pixels. Optionally, the tile cross section is stored in solid state/local memory during the rendering process, and optionally is not persisted to nonvolatile memory, such as a magnetic or optical disk device.

At state 5, the tiles are optionally stored to a disk device by copying the pixels referenced by a corresponding tile matrix and encoding them (e.g., to PNG format).

At state 6, a cleanup process is performed. After tile persistence to memory, the tile is released. After the last tile is in a strip is persisted, the strip is released. After the last strip in a zoom layer is persisted to memory, the master tile is released. After the last instruction set in a render instance request is complete, the source tile is released. Releasing involves clearing the objects from memory.

At state 7, the rendering request is marked as complete (e.g., by renaming the file to indicate the corresponding is complete, such as “Done-000000x000000”). The file naming convention may be specified by a respective portal. For example, the file name may include a primary key of the drawing (optionally padded by zeros or other number), followed by a primary key of the drawing version. The portal may retrieve the completed files and update the database with the appropriate status.

Optionally, in the event of an error, such as malformed request, improperly formatted input document, or insufficient disk space, the file name may be prefixed with an error indicator (e.g., “Error”) and/or an error message/comment may be written into the configuration file, and/or an error notification may be written to an event log.

Drawings may be displayed by stacking a series of layers using a combination of canvases (e.g., HTML5 scalable vector graphics (SVG) canvases). A given layer may indicate drawing additions and/or deletions. In the case of an overlay, two or more drawing layers may be stacked on top of a white canvas. Because the tiles are transparent, a user can see through the layers enabling the user to view additions or deletions between the layers. A control may be provided enabling the user to instruct the system to toggle the layer order, thereby enabling the user to flip between additions or deletions respectively. The user may also instruct the system to change the color of a layer to a specified color.

Sketches or vector paths may be stacked on top of the foregoing layers. A sketch may be in the form of a series of points representing a geometric shape, which may represent a building feature or other feature. The points are stored to the database in a specified format (e.g., a WKT (Well Known Text) format). The sketches/points may be rendered on the drawing using SVG (Scalar Vector Graphics).

Measurements may also be displayed using SVG, but optionally are not persisted to the database. The measurements may include areas calculated from regular or irregular polygons.

A user may instruct the system to print one or more drawings. The system may perform printing in a vector fashion. When a print request for a drawing comes through, either as a single or via a batch, the system opens the source file (which may be in the form of a PDF file), injects print objects, and then feeds the document to the printer in substantially real time.

A given sketch may be written into the source file after the coordinate system is translated. The coordinate translation optionally takes into account for zooms, rotations, and a dynamic document size.

The system optionally is configured to display a document for review in a browser without requiring any plugins to be installed (e.g., without Flash or Adobe Reader).

Certain embodiments of the plan management system enable various stakeholders to add comments to an electronic plan/design document. By way of example, for a building plan, the stakeholders may include various departments in a government plan checking agency or architects, engineers, contractors, consultants, construction project managers, etc., that are involved in reviewing, commenting, and requiring changes to building related plans. The comments may be tied to a specific building feature in a plan drawing or to a specific location on the design drawing. The comments may also apply to the project overall and need not be directly associated to a specific building feature or location. Of course the stakeholders may be different with respect manufacturing documents, design documents, or other document types.

A comments data store, (e.g., with a table structure) is provided that is configured to store, in a searchable form, comments, properties, and metadata associated with a given project or permit application and which may include references to one or more specific plans or plan sheets. For example, a given comment record may include or be linked to some or all of the properties and metadata discussed herein. In addition, a standard comments table may store a library of reusable comments that may be accessed by a user and added to/associated with a project/permit and its specific plan sheets. Users can add terms or properties to a given comment type to facilitate the organization, grouping, and reporting of those comments.

Thus, the comment tables provide users and administrators the ability to search for comments by entering a search string into a search field and/or by selecting properties/metadata from a filter menu. By way of example, a given comment may be associated with metadata including author, date of creation, modification history, modification authors, comment status information, categories, subcategories, project type, discipline, etc. Optionally, the plan management system and/or an administrator/user may specify which users may assign or associate certain metadata with a comment (e.g., a category, subcategory, discipline, and/or project type).

The system enables a user to conduct searches on comments including the standard comments table and to save a search query or a group of search queries to memory. Users may save their own searches for reuse and may retrieve and modify their searches via a labeled “favorites” control. The user can assign a user-defined label, which may be descriptive as to the subject matter of the saved search queries. Additionally, a user may retrieve and run saved standard comment searches created by other users, however, optionally the system may prevent a user from modifying another user's saved searches.

Drawing comments may be associated with an image tag pasted into the drawing document (e.g., with a text label placed on top of the tag corresponding to a comment number or other identifier). Optionally, additional metadata may be associated with the tag (e.g., the full comment that appears when the user hovers a mouse over the image tag).

As noted above, in addition to being able to search for text within comments, comments may be searched on based on one or more comment properties or metadata (or the lack thereof). For example, a user can search for comments in a permit/project which have not been associated with X/Y (latitude/longitude) coordinates on plan reviews.

A given comment or group of comments may be assigned a label or flag indicative as to the subject matter and/or functional use. For example, a given comment or selected group of comments can be labeled as a “checklist” item. The system may display comments in a list format in a panel or window, rather than simply at various locations distributed over a drawing. A ‘checklist’ item denotes a comment/review which the designator indicates must always be performed by the plan reviewer, based on the business rules in place for the user. For example, checklist item may include a check to make sure that building modifications proposed in a plan do not fall outside a property line. A standard comment may or may not be designated as a ‘checklist’ item.

In addition, users and administrators can import, create, and maintain one or more libraries of standard comments for reuse, and define groupings of standard comments by department or other organizational group. Optionally, the comments may be edited, stored and displayed in a rich text format, HTML, or other format that encodes text formatting properties, such as bolding, underlining, italicizing, and typefaces, and to provide support for tab characters, carriage returns, and numbered or bulleted lists. Optionally, only certain authorized users, such as administrators, may be permitted to edit or modify standard comment text. Certain embodiments enable comments stored in another document type, such as a spreadsheet or word processing document, to be batch uploaded into the standard comments table for later user access.

In addition, a correction list, such as might be specified by a plan checker or architect, may be automatically grouped/generated and formatted based on a user specification. The correction list may then be provided to the applicant, architect or other end user. After the applicant has corrected the noted items, the applicant may resubmit corrected plans (also referred to as a resubmittal) for plan check and approval. Optionally, this process of reviewing the plans, requiring corrections and resubmitting corrected plan sheets may continue until all the respective plan reviewers determine that all outstanding issues have been resolved and the permit can be issued by the appropriate governing agency.

A user may select one or more comments or groups of standard comments, and insert them with a command (e.g., a single command) into a permit/project plan review data record. Optionally, a user may choose to associate a comment with one or more plan review sheets and set an X/Y coordinate with a command (e.g., a single command). Optionally, comments that are associated with action items or that need to be reviewed (e.g., in progress reviews) may be assigned by respective departmental queues and displayed as such.

Comments may be displayed in one or more scrollable, collapsible panels/windows, optionally at the same time a plan drawing (sometimes referred to as a plan sheet) is displayed. Optionally, the system automatically and/or in response to a user command refreshes displayed comments so as to include any changes by other users.

Optionally, the system enables batch uploading of plans and supporting documents into the system by a user and further provides batch assembly of plan sheets and supporting documents into a file, such as a compressed vector file (e.g., a PDF formatted document compressed into a ZIP file). Optionally, the system enables the assembly of single sheet PDF documents into a multi-page PDF document.

Certain example user interfaces will be discussed with reference to the figures. It is understood the other embodiments of the user interfaces can include fewer or more features, and that a given user interface or a portion thereof can be combined with another user interface or a portion thereof.

FIG. 2 illustrates an example drawing review user interface. The user interface contains a plan panel 202 displaying a building-related plan sheet, and related tools 204. A given plan sheet may have multiple layers. For example, a given plan sheet may include some or all of the following layers: document, comments (open and/or closed), sketches, approval stamps, measurements, or closed comments. Programmatically, the application may create virtual layers stacked on top of (or below) the plan review drawing which allows for sketches (boxes, circles, lines, etc.) to be managed as a whole for the particular sheet. In certain embodiments, the plan sheet may be disassembled as a series of image ‘tiles’ converted to another format (e.g., a PNG format) by a rendering engine. Additional layers for managing comments, digital stamps and measurements may also be created virtually.

The user can instruct the system to make a given layer invisible or visible. When requested, the plan sheet and associated layers, with their objects, can be assembled and re-rendered as a PDF document by the system. The information in a given layer may be provided/created by one or more entities, such as an architect, contractor, or plan checker/permit approver. The application provides the ability for multiple users to modify the same plan sheet concurrently, in substantially real time, and optionally ensures that a given modification made by a user is made visible to other users when a ‘save’ or ‘refresh’ operation is performed.

The tools may include drawing tools (e.g., to draw lines and shapes, add objects from a library, etc.), analysis tools, and file tools (e.g., save, open, PDF export, download, overlay, etc.). A summary pane 206 displays summary information regarding the displayed plan sheet, including for example, a unique plan identifier (e.g., a plan review number and/or physical address associated with the construction project), a drawing sheet number of the displayed plan sheet, a description (previously entered by a user), a submittal number (which may be used to manage/group plan sheets which have been corrected and resubmitted for subsequent plan check), department information (e.g., of departments or other organizational entities that are tasked with performing a plan review), version number, and application contact.

In response to a user activating the illustrated “view attachments” control, the plan management system will retrieve, from local or remote memory, and display previously stored related documents. Typical examples of such attachments may include a copy of the permit application, a soils study document, calculations (e.g., related to energy efficiency, square footage, etc.), a photo image (e.g., of the site), a spreadsheet or word processing document saved in native or PDF format, etc. These documents may be accessed by the user for viewing (e.g., by downloading or viewing via a browser) as well as for the digital application of a stamp or seal. In response to a user activating the illustrated codes (“ICC codes”) control, the plan management system will access and retrieve from a remote standards database (e.g., the ICC (International Code Council) database), and provide the user with access to, some or all of the corresponding code tables. Optionally, a search field may be provided via which the user can search for particular ICC codes. Optionally, the search may be submitted to the remote database, which will conduct the search and return a result. Optionally instead, the search may be performed on a local copy of the ICC code tables. In either case, the user can add an associated ICC comment into the plan (e.g., into the plan panel 202 or the drawing comments area), and edit the pasted comment. This speeds up the comment entry process and reduces the amount of errors that may occur relative to a user manually typing in a code comment. Other industry standard code databases or websites can also be made available to provide the foregoing or similar functionality, as desired by the user.

Zoom controls 208 are provided via which the user can instruct the plan management system to zoom in or out, at various levels, with respect to the displayed sheet.

A drawing comments area 210 lists the comments associated with the displayed plan sheet. If the space provided in the comment panel for a given comment is insufficient to display the entire comment at once, only a portion of the comment may be displayed in the panel (e.g., the first 50 characters). The comments list may be scrollable so that a user may scroll through a list that is longer than can be displayed in the area provided. In this example, a given comment is associated with a unique comment identifier, referred to as a comment ‘tag’, with respect to the displayed plan sheet. In the illustrated example, the identifier is numerical, although the identifier may be an alphabetical, alphanumeric, graphical, and/or other type of identifier.

The user interface illustrated in FIG. 2 also provides a comment log control, which when activated causes the system to open a new page which generates a comprehensive table of comments for the given permit/project and any associated plan sheets (see FIGS. 9A, B, 10, and 11 which illustrate different sections of an example user interface), and metadata recorded by the system or user. This data may be filtered in a number of ways by the user and can be used to automatically generate a correction list for the permit applicant or end user, in response to a user activating a corrections report control provided via the comment log user interface. The comment log user interface page may include several sections, including, by way of example, a search panel, a search results panel and a comments editing detail panel, examples of which are described below with respect to other figures. The user may choose to select a comment from the list and choose an edit comment control which may allow for editing of the comment detail.

A refresh control is provided, which, when activated, causes the application to re-query the comments table for the particular permit/project to display any changes made since last refreshed. A “+” control is provided which, when activated, causes a comment data entry form (e.g., a single comment data entry form) to be displayed via which the user can enter a comment which will be added to the displayed plan sheet at a chosen X/Y coordinate. When a user clicks on the small open or closed circle placed to the left of the comment in the panel list, the system causes the plan image to shift until the selected comment identifier/tag is placed in substantially the center of the drawing review page.

When a user hovers a cursor or otherwise points to a given comment on the drawing review page, the comment is displayed in a pop-up window panel 202, optionally in association with an element in the plan (e.g., a structural, plumbing, electrical, or fixture element). For example, there may be a visual association between the comment and the element, such as a line connecting the comment to the element, or a highlighting of the element associated with the comment. The comment text may be displayed “in full” or at least to a greater extent than in the comment panel list. The user may also request that the plan management system format and display the comments via a PDF document, XML documents, or the like.

A drawing layers control 212 is provided via which the user can specify which layer of the plan sheet is to be displayed (e.g., document, comments, sketches, approval stamps, measurements, closed comments, etc.).

FIG. 3 illustrates an example comment in a pop-up window. The comment includes a departmental identifier in association with the assigned comment tag number shown in the comment list or panel control.

As illustrated in FIG. 4, the plan management system is configured to generate a PDF document (or other specified document format) of the plan sheet including sketches, stamps and other modifications, accessible by a PDF viewer application (or other applicable view application), which properly displays the comment identifier tags, comments as pop-up windows and an embedded list of comments from the comments table.

As noted above, the plan management system facilitates plan checking. For example, a plan may be submitted for approval, such as to a governmental agency, for plan check. Multiple departments may be involved in the plan check process, such as a building department, fire department, water department. In an example embodiment, after intake for plan check, a drawing status for given plan sheet and a respective assigned department is set (automatically or manually) to Not Started,' and the drawing records are sent to a queue for pickup by the appropriate department or an assigned user. Once a departmental plan checker starts their departmental review, the plan management system will change the sheet status—for that department—from ‘Not Started’ to ‘WIP’ (work in progress). As a permit status or departmental workflow statuses are changed, the plan management system creates an audit record in the event log table.

After the departmental review is completed for the plan sheet, the plan checker may change the workflow status to ‘Approved’ or, if there is a correction need, to ‘Resubmit’.

The plan management system may monitor the status of each plan sheet with respect to each department, and when the plan management system determines each departmental review has been completed, (e.g., all the drawing statuses have been set to Approved or Resubmit), the plan management system automatically changes the permit status to ‘Ready to Issue’ and notifies the appropriate personnel (e.g., permit supervisor) via email, instant messaging, SMS, MMS, or otherwise.

FIG. 5 illustrates an example workflow assignment. In this example, three departments (Building, Fire and Water), each with an associated data record and workflow, are assigned to review the same plan sheet. Each department can assign their own review disposition/status (e.g., resubmit for approval, not started, work in progress, etc.). Thus, the drawing data records created for a given sheet and associated with a given department may be managed via the department's own workflow process.

As noted above, the plan management system may provide a library of commonly used or standard comments which optionally come pre-populated with a standard installation of the plan management system, or which can be imported into the standard comment table by a user. A user may select and customize a standard comment from the library or create a new standard comment, which can be selected by a plan review user to link to/associate with a given plan sheet or to include in permit/project review as a whole, without a specific sheet assignment. Thus users/administrators are provided the ability to customize the standard comments and review comments to fit the needs and terminology of their particular agency via a list management user interface.

FIG. 6 illustrates a table of lists describing example uses for various items of metadata, although the metadata can be used for other purposes as well. As illustrated, metadata includes a category (which may be used to manage, group and sort a given plan reviewer's comments and corrections, such as those included in a correction list). In addition, a code table is provided, which identifies code tables (e.g., IRC (International Residential Code), CBC (California Building Code), etc.) used with a relevant agency, such as a governmental plan check agency. The metadata may also include a contact method, a construction type code (e.g., as specified in a code table), a contact method for the applicant/owner, a department identifier for a user or plan, acceptable drawing sheet dimensions as specified by a relevant governmental agency, a list of industry standard disciplines, a compass direction associated with an address for the property corresponding to the plan, disposition of a comment (e.g., open, closed, etc.), document type (corresponding to a value for an incoming file and/or attachment received by the plan check system, and impact, which defines the importance designation for a plan reviewer comment (e.g., open, closed, etc.), and occupancy codes as published by an agency (e.g., industry code as published by the CBC in 2012). The metadata may also include a permit priority (e.g., agency-specific terms reflecting the priority of the permit application and/or expected turnaround by the reviewing agency (e.g., overnight, high, normal, etc.), permit type (e.g., agency specific terminology: roof, pool, electrical, etc.), project type (e.g., agency specific terminology: residential, commercial, zoning), street type (e.g., commonly used street type designations, such as avenue, boulevard, zoning, etc.), sub-category (e.g., an agency list and sort order of comments that will be used on the correction list), and submittal (e.g., agency specific permit submittal language (e.g., 1^(st), 2^(nd), 3^(rd), etc.).

A system list may include access (e.g., manager user roles and system security roles), permit status (e.g., defines current workflow status of a permit record, such as open, on hold, withdrawn, ready to issue, issued and resubmit, etc.), and drawing status (e.g., defining the current workflow review status of a drawing, such as not started, WIP (work in progress), resubmit, and approved).

Each agency/department may edit a descriptive item label, and assign its own alpha/numeric codes to a given entry. These lists may be presented throughout the plan management system user interfaces, such as in dropdown controls or menus that are used for filtering, searching and sorting comments, as well as in generated reports, such in report graphs, charts and timelines.

FIG. 7 illustrates an example administrator user interface for administering and managing standardized comments, where end users may then add the comments to plan sheets or checklists. Administrators can batch upload standard comments, classify a given record by discipline or project type, category and sub-category, and/or checklist identifier. This helps manage comments, and defines the grouping and sorting of correction list reports. For example, an administrator may mark certain comments as being “checklist” comments via a checklist field (e.g., the Chklst column), where a checklist item has to be checked off in order to receive plan approval. The user interface further enables an administrator to specify a project type, discipline, a category, and a sub-category for a comment. For example, project type or discipline may include “mechanical,” plumbing”, “RE INIT (Residential Initial Review),” “structural,” etc. The categories may include “A. Permit Applications,” “Part 1: General Requirements”, “Part II: Zoning,” etc. The subcategories may include “A. General Requirements,” “A. Permit Application,” “B. Clearances,” etc. The values displayed in the dropdown boxes can be edited and updated by the users, so the data in each list may vary from agency to agency.

A sort control may be provided, which, when activated by a user, sorts the comments to preview the order in which the comments will appear in the correction list. The user interface enables the user to specify what sheet comments are to be included in a correction list, the order and groupings in which the comments are to be presented, and the appearance of the comment text (bolding, italicized, etc.). For example, the user may want to specify that general comments are displayed above structural comments, application comments are to be displayed above administration comments, etc. The user interface may enable the user to sort on discipline or project type, category and subcategory, a free form text field labeled ‘section’ for storing building code information, the text of the standard comment, checklist flag, creation date, and status (e.g., active or inactive). As discussed with respect to FIG. 18, the plan management system can render a customized correction list report in accordance with the user's specifications. The system may inhibit comments designated with an inactive status from being displayed to plan reviewers via the search tool of the standard comment library.

As similarly noted above, administrators can batch upload standard comments into the standard comment table from a document, such as an XLS or CSV document, before or after which, a user may format the standard comments to reflect bolding, italicizing, bullet and numbering and hyperlink formatting, classify a given comment record by discipline or project type, category and sub-category, and flag a given standard comment as a ‘checklist’ (or required for review) item, as illustrated in FIG. 7. This ability to classify comments not only helps manage the comment library, it also enables a user to locate a desired comment quickly and efficiently, but may also be used to define the grouping and sorting and placement of the comments on the correction list reports.

As illustrated in FIG. 7, an “add comment” control is provided to allow a user to manually add a record to the standard comment table. A print control causes the application to open a report of the comments in a PDF document. A search control is provided via which the administrator can search for standard comments by specifying query text and optionally fields where the text is to be found.

The plan management system can record and track, in substantially real time, users' actions and permit status. For example, the plan management system can track how many permits have not started the review process, the number of resubmits, the number of work in progress, or approved overall and/or by department. The plan management system can also track comment status by department (e.g., how many are open or closed), how many drawings have been accepted by department, and submittal counts by department. The plan management system can analyze the recorded information and generate reports in substantially real time, including graphs, reporting the foregoing information. For example, a report can be generated reporting permit count status for each status type for one or more periods (e.g., on a month by month basis) using a bar-type graph. Further, the plan management system can generate a report of current comment status by department, submittal counts by department, and drawings accepted by department. Example graphical reports are illustrated in FIG. 8. The recorded and reported information can be exported via one or more different formats, such in a CSV, RTF or DOC file, or other word processing, spreadsheet, or database document/file.

As discussed above, certain embodiments of the system provide extensive search facilities. As illustrated in FIG. 9A, a search user interface enables a user to search for comments based on some or all of the following criteria: by department, disposition/status, reviewer ID, sheet number, comment type, discipline or project type (e.g., electrical, plumbing, structural, etc.), comment text, category, sub-category, submittal identifier, record number range, reviewer firm, comment date range, etc. Thus, using the illustrated user interface, a plan checker can search for and view comments placed by any user in any department (unless otherwise restricted by an administrator). The user interface enables, for example, a department to group and sort their correction lists by categories and subcategories. An administrator can specify which users may edit, add, and/or delete comments (e.g., based on user roles).

A user can also search the standard comments library for a desired/appropriate comment, and then, via the search results, select and insert one or more located comments into the comment log table for a permit/project as well as on a specific plan review sheet. Then, as similarly described above, on the plan review sheet, tagged comments are displayed in a list in automatically numbered tags. The tagged comments appear as pop-ups over the plan sheet (optionally in association with the item being commented on) when a user hovers a cursor over the comment in the list. A tagged comment may optionally include an x/y coordinate indicating the item in the plan sheet that the comment is associated with or where the comment is to be displayed. The system may substantially center the portion of the plan sheet corresponding to the x/y coordinate in the plan sheet review display area.

FIGS. 9a, 9b , 10 and 11 depict snapshots of an example Comment log page.

Referring to FIG. 9A, a “simple” search control is provided, which when activated, causes a simple text search user interface to be displayed, as illustrated in FIG. 9B. The user can enter a text string and the plan management system search engine will search for matching comments, and return the matching comments for display to the user. The illustrated example simple search interface does not include additional filtering menus.

Referring again to FIG. 9A, an “advanced” search control is provided, which when activated, causes an advanced search user interface to be displayed, providing extensive user selectable filtering of comments by department, discipline or project type, category, sub-category, submittal, disposition, impact, sheet number, user, date ranges, etc., optionally in addition to providing a field configured to receive a textual search string. Examples of advanced search user interfaces are illustrated in FIGS. 9A and 12.

FIG. 10 illustrates an example search result for a search performed using the search user interface of FIG. 9. The search results in this example are presented via a table, including columns corresponding to sheet number, comment number, comment text, applicant response, disposition, department, discipline or project type, and impact. An upload control is provided via the search result user interface, enabling users to upload attachments in a desired format to a specific, user-selected comment record which the plan management system links to the comment. These uploaded files are retained as ‘attachments’ and can be returned to the permit applicant with the plan comments. An attachment report control is provided which when activated causes a new window to open, displaying a report (e.g., in PDF format) including the file name, department, plan sheet number and comment text of any external documents which have been uploaded and linked to one or more comments. (See FIG. 16b ). A comment report control is provided which when activated causes a comment report to be generated, as described elsewhere herein. Controls are provided via which a user can instruct the plan management system to export the search report, or a user selected portion thereof, to a file in a specified format (e.g., Excel, RTF, etc.). An “ICC code” control is provided, which when activated, causes the plan management system to retrieve from a remote standards database (the ICC database in this example) some or all of the ICC code tables, and display or otherwise provide user access to the codes.

As illustrated in FIG. 10, a pop-up menu is optionally provided, which may be accessed via a mouse click or otherwise. The pop-up menu includes a plan review option. If the comment record contains coordinates with respect to the plan sheet (e.g., x/y or polar coordinates), activating the plan review option causes the plan management system to open the drawing and the corresponding comment tag in a new window. The pop-up menu may also include an attachment option. If the comment is linked to an attachment, activating the attachment option will cause the plan management system to open the selected file in a new window. The pop-up menu may also include a delete option, which when activated causes the plan management system to delete a comment selected by the user if the user has rights to make such a deletion. FIG. 10 also provides an “add standard” control which causes the application to active the standard comment search interface (see FIG. 12).

FIG. 11 illustrates a single comment detail user interface for viewing. If a user selects a comment record from the search results of FIG. 10, the plan management system will provide for display details for the selected comment in an Add/Edit Comment area/pane. The comment detail user interface displays various metadata associated with the comment, such as department, disposition/status, reviewer ID, sheet number, comment type, discipline or project type (e.g., electrical, plumbing, structural, etc.), comment text, category, submittal, record number range, reviewer firm, sub-category, and/or comment date range. In addition, the comment detail page provides the history of the comment, back-checks (e.g., internal or public comments to original comment—where multiple levels of comments may be recorded and displayed), etc. If the user selects the edit comment control, the system activates a data entry interface (See, e.g., FIG. 15).

FIG. 12 illustrates an example user interface for performing searches, including Boolean searches, of standard comments. A field is provided via which the user can enter a search string. In addition, the user can specify via respective controls whether the plan management system search engine is to only identify comments including the exact phrase entered into the search field, all comments that include all the words of the search query (but not necessarily in the same order or directly adjacent to one another), or comments that include any of the words included in the search query. In addition, filter menus are provided via which the user can select/specify additional search limitations. For example, a user may specify that only comments associated with a specific project type/discipline (e.g., architect, access, electrical, etc.), category (e.g., means of egress, modification/programming correction, new category, occupancy class, etc.), and/or subcategory (e.g., exterior walls, fire barriers, fire walls, floor plans, etc.), in addition to matching the search string, are to be identified to the user.

The right side of the user interface illustrated in FIG. 12 displays the matching comment(s) identified by the search engine, including the parameters that match the additional filters (e.g., category, subcategory, etc.), in a sortable table (which may be sorted on one or more of the table fields). A checkbox filter option labeled ‘ChkList’ is provided in association with a given search result which if chosen, will cause the system to retrieve and/or display only those standard comments which have been designated as a checklist item. A “Select all” checkbox is provided to the left of the Category column in this example, via which the user can select or unselect all of the comments provided in the search results.

FIG. 13 illustrates an example standard comment search result. In this example, no search text was entered into the search field, but several filter items were selected by the user. In particular, the user selected structural comments (comments associated with the structural discipline) assigned to the zoning category. The search engine returns matching standard comments in the scrollable, sortable, search results panel on the right, including the category and subcategory parameters. The user may select, by checking an appropriate check box, one or more comments, which will then be automatically copied from the standard comment table to the permit/project's comment table, where they may then be associated with one or more plan sheets. These comments then may be published on the correction list provided to the applicant. After the applicant/owner has corrected the noted items, the applicant/owner may resubmit the corrected plans for another review.

FIG. 14 illustrates an example saved standard search control. A user can perform a search of the standard comment table and choose to save the search query for later use as a favorite or otherwise by activating a save search control, and entering a descriptive search name. The user may select an option control to indicate how the search terms should be handled by database query, such as exact phrase, all the keywords, any of the key words in order to show the query parameters that were entered and saved by the user. The user may also select a checklist items checkbox as appropriate. The user may later retrieve the saved search query by name, and search for comments using the retrieved search query.

FIG. 15 illustrates an example user interface for editing a reviewer's comment. A user editing or drafting a comment can select from one or more menus and/or enter into one or more fields a variety of properties to be associated with a comment, and which may be used to group and sort comments. For example, a user can specify a department, comment impact (e.g., major, minor, medium), category, disposition (e.g., open, closed, etc.), submittal number (e.g., 1^(st), 2^(nd), 3^(rd) submittal), item (e.g., used to add additional information, if desired), comment number (which may be unique to the respective plan sheet), reviewer organization/firm (e.g., municipality, architect, contractor, etc.), and/or detail number. Fields and/or menus are provided via which a user can specify the relevant drawing sheet, version open (in such embodiments where the system will only allow comments to be placed on the most recent version of a plan sheet, so version opened and version closed controls will display each version for reference purposes only), and coordinates (e.g., X/Y or polar coordinates). The user can activate a remove control to delete the comment, an edit control to edit the comment, and a review control to preview, in a “review comment” field, how the comment will look when presented via the comment list. Rich text features (e.g., for adding bolding, italics, numbering and bullets) and hyperlinks may be used in editing the comments. A backcheck field is provided for recording subsequent notes about the initial review comments. A 2^(nd) backcheck field is provided to record a response to a back check comment.

FIGS. 16a and 16b illustrate another version of a user interface for editing a plan review comment. This example has fields for receiving and/or displaying the following: reviewer, submittal number (e.g., 1^(st) submittal, 2^(nd) submittal), department, discipline, impact, item, comment number, category, sub-category, disposition (e.g., open, closed, etc.), detail number, and reviewer comment. Optionally, the values in the category and sub-category menus (and/or in other menus) may be customized by a user/administrator. The values selected an end user/plan checker enables the comments to be automatically grouped and sorted in a correction list report returned to a permit applicant. The comment and field values may be saved to the database by activating a “save comments” control. The item field is provided to receive additional information that users/plan checkers may wish to include on the correction list. The detail number field is also available for other notations, as needed or desired.

FIG. 16b illustrates additional comment fields for optionally including backcheck comments following reviews of resubmitted plans. A given comment field supports formatting controls for bolding, italicizing, bulleting and numbering. Additionally, a file upload and attachment control is provided which allows the user to attach an external document in any format to the associated comment record. These attachments may differ from the attachments linked to the permit/project under review in that they themselves may be provided for the applicant's use or information, rather than as a supporting document which needs to be approved by the plan reviewer or agency.

FIG. 17 illustrates an example user interface for associating a comment which has been added to the permit/project comment table to one or more specific plan sheets. Fields are provided via which a user can specify a sheet number, and view any sheet version opened date stamp, a version closed date stamp, and coordinates specifying the location where the comment tag is to be linked graphically on the plan review image. A new or existing comment can be linked to a specified plan sheet number and open or most recent version by selecting the sheet number from the drawing sheet control. The same comment can optionally be linked graphically to any other sheet belonging to a respective permit by activating the ‘Add Drawing’ control and then specifying the drawing sheet number. Additional controls for removing the comment from a plan sheet, for opening the drawing sheet on the review page, and for auto-centering the comment on the screen are also provided for the user.

FIG. 18 illustrates an example correction list report. Using the automatic numbering of comments, and the built in association of a given comment to a discipline, category and sub-category list, each with their own order by value, the plan management system can produce a correction list report, with rich text formatting over which a user can manage the primary (discipline), secondary (category) and tertiary (sub-category) header names used in the report template. Thus, the user can manually, or the system can automatically generate a polished correction report using plan sheet comments, customized to a given entity's/agency's needs or specifications. Optionally, the correction list can aggregate and integrate plan review markups and comments from multiple departments into a single report, eliminating or reducing the need for each department involved in the plan check to issue its own separate report. The user may tightly or loosely control which comments to include on the correction list by selecting/setting one or more dropdown controls available in the search plan review interface as shown in FIG. 9a or FIG. 9B.

In this example, the correction list is organized to list the category “building” comments first, and within the category of building comments, to list the application subcategory comments first and the administration subcategory comments second. The system may access and display in association with a given comment an associated sheet identifier (e.g., [#E100]) of the plan sheet the comment is associated with and a comment tag number (e.g., [0004]). The comments may include corresponding building code numbers/identifiers where the comments are extracted from a building code data store (e.g., the ICC code table). The correction list report may also identify who is performing the plan check and the plan checker's contact information. Users can preview the permit's corrections/comments log by activating a preview control.

As noted above, certain embodiments enable a user to batch import standard comments into the system and to record metadata for each review comment. FIG. 19 illustrates a list interface illustrating certain metadata assigned to lists being imported. A list type is selected (e.g., Disciplines or Project types, Category, Subcategory). An order value may be assigned which may be used by the system to sort the correction list headings in numerical order in accordance with the order number (e.g., display order lcomments before, order 2 comments, display order comments before order 3 comments, etc.). A primary key (PK) value is a unique identifier assigned by the system, where a given list has a unique code. The system may use the primary key value to import standard comments from a file, such as an XLS spreadsheet file, and to link the incoming comments to matching List records. A user may assign a label to the list that describes the list. The system may display the label on reports, such as on correction list reports. A value, which may be a descriptive short name (e.g., an abbreviated version of the label) or a code, may be entered by the user. The value may be used by the system on controls, graphs, timelines and reports.

In the example illustrated in FIG. 19, based on the order numbers, the ‘Residential Initial/RE INIT’ comments will be positioned at the top of the Correction list, followed by architectural comments, mechanical, etc. Optionally, the system allows comment records to be assigned the same order number and does not require sequential ordering of records.

The correction list reports may be grouped by the discipline, then by the category and then by a subcategory, using the order number and then the label value. Where two or more records have the same order number, in certain embodiments, the records having the same order number may be sorted by the system alphabetically or using other criteria. The foregoing features enable different agencies/entities flexibility in defining how to group list records.

By way of illustration, in the example illustrated in FIG. 20, for the list type “Category”, the user has created a numbering scheme within the Label and Value columns and set the ordering for each record. Similarly, in the example illustrated in FIG. 21, for the list type “Subcategory”, the user has created an alphabetical ordering scheme within the Label and Value columns and set the ordering for each record.

Once comments (e.g., standard comments) have been uploaded or manually entered into the database, an administrator can check the information to see how it will ‘sort’ on the correction list report. This validation can be run on all standard comments, or on a filtered set of comments. A user can activate a sort control and the system uses the PK values in the comment record to locate corresponding order values in the list tables and to sort the results accordingly. The user can change the sort as desired. For example, the user can modify the order values in the discipline, category and sub-category records from the list management user interface, and the system will resort the comments accordingly.

Thus, as described herein, certain embodiments enable a user to add comments, such a plan check comments, to plan sheets, and to search, filter, and report on comments added to an electronic building related document. Further, certain embodiments enable a user to upload standard comments en masse. Yet further, certain embodiments enable that automatic generation of correction lists, including comments from multiple departments.

While certain embodiments have been described with reference to the management of building-design related documents for illustrative purposes, embodiments described herein can likewise be utilized for managing manufacturing documents, clothing design documents, or other types of design documents.

User interfaces described herein are optionally presented (and user instructions may be received) via a user computing device using a browser, other network resource viewer, or otherwise. For example, the user interfaces may be presented (and user instructions received) via an application (sometimes referred to as an “app”), such as an app configured specifically for building plan-related activities, installed on the user's mobile phone, laptop, pad, desktop, television, set top box, or other terminal.
